Qualcomm already has their own blanket license and their own custom cores. Nuvia's license only covered server products, so Qualcomm could not use the acquired license anyway.
ARM claims that Qualcomms pre-existing license does not allow "technologies developed by third parties under different Arm licenses".
So I guess the case will come down to arguing if an acquired company counts as "a third party" or not
It also comes down to if the courts will allow exclusion of "technologies developed by third parties under different Arm licenses". In some cases the courts will determine some clause like that grossly unfair and so not enforceable. (seems unlikely, but type of thing can happen)
And what is a "technology". Can you literally not use anything patented by a third party ever? In court cases like this, technicalities like this matter a lot.
